WINDING-SPINDLE;

Specification of Letters Patent. i Patented Sept.

Application filed May 27 1911. Sefial'Noi 629,809.

To all whom it may concern Be it known that I, RAY S. A'rwoon, a citizen of the United States, residing at Plymouth, in the county of Luzerne and State of Pennsylvania, have invented'new and useful Improvements in Winding-Spindles, of which the following is a specification. j

The present invention has reference to spindles for carrying bobbins onto which silk is wound preparatory to being spun or twisted, and it comprehends an improved spindle construction designed primarily to overcome certain defects which exist. in many of the forms or types of spindles" now in more or less general use. i

The best known forms of spindle are provided at one end with a removable wooden roll or head which is secured thereto by a' the spindles are tightened up, the rolls being forced out of place, with the result that the traverse of the thread is impaired; also,

the employment of the pins renders the removal of the roll extremely difficult, since the use of boring or drilling tools is ordinarily necessary. i v

Inthe improved construction, a special locking device is utilized to hold the roll in place and prevent it from working loose, thus checking the tendency. of the bobbin to overrun at one side. This deviceconsists, briefly, of a fiat metal disk or washer which is locked upon the spindle ina particular manner and is arranged to contact squarely against the adjacent face of the roll, but which can be readily removed when occasion arises. I, l A structural embodiment of the invention is illustrated in the accompanying drawing, whereof-- Figure 1 is a side elevation of the spindle,

with the roll, bobbin and clamp in place thereon; Fig. '2 is a similar view, withathe bobbin omitted, the roll in section, and the clamp removed; Fig. 3 is an end view of Fig. 2; Figs. 4 and 5 are end viewsof the roll; Figs. 6, 7 and 8am detail views, respectively, of the spindle, washer and clamp.

The spindle 1, as shown in saiddrawing, has a generally tapered form, is provided at its larger end with a terminal stem 2 of re ducedldiameter and adjacent its smallerend with a threaded portionf3j, stem 2v being formed at its pointof junction to the spindie bodywith a retaining recess 4, here depicted as acircumferential' groove 4. Groove 4 serves as" a seat wherein the washeriiele ment 5 of' the,aforementioned lockingfde vice is anchored. Thisfielement is consti tuted, inflthe present instance, by aiflat' steel disk in which is formed a keyhole slotfi, the outer portion of said slot having, the. same diameter as the spindle stem 2,,while f nner portion is of the same diameter, asithe bottom wallof i'ally of the, disk.

Disk 5 is designed. to fit in," countersunk seat 7. formed'in the outer end face of the wooden roll 8, which latter, in turn,} j is mounted upon the spindle body, being pro vided for that purpose with an axial bbrea To prevent said roll from turning upon: the

spindle, thela'tter may be provided with grooves is locatedjam spurs 10 that are struck up therefrom and it are arranged to u branchesll of the roll bore 9,,saidbra'nchs 'dle there is associateda clamping member 12 adapted to be tightened againsttheadproject. into longiti dinal" opening through thei-nner end face of'said jacent 'endface ofthe bobbin 13, the other end face of wh-ich latter bears flush against the inner .end face. of the roll. In the :con- 1 struction illustrated, the clamping member consists of a metal strip "provided with an enlarged central bearing portion lthrough which is formed a "threaded opening 15,- the ends 16* of the strip being slightly curved, as shown, to [produce handles by means whereof the strip may be turned.

In assembling the parts, the roll 8 is fitted I,

T uponthe left-hand or stem endof the spine die and then forced toward-I the right until the left-hand end face of said roll haslbeen moved re groove Lille spurs 10 being caused toQenter the branchesgll of the; roll bore during the movement of the roll The Washer disk 5 isnext fitted. Ont-he spindle stem and anchored in saidgroove by, first slipping said stem through the enlarged outer portion of slot 6 until thegroovegis reached, and then moving said. disk in the proper direction to engage the smallerjinner portion of theslot with the'bottom wa ter the groove, in which position the shoulders produced by the formation of the, groovp, j

(i. 0., the side walls thereof), will bear directly against the opposite faces of the disk, and will, in consequence, hold the latter firmly in place. The bobbin and clamping member are then successively mounted upon the spindle, after which said clamping member is tightened up against the bobbin in the obvious manner, with the result that said roll. is forced back slightly toward the disk, which latter is thus caused to enter seat 7 When the parts are thus assembled, it will be apparent that the roll. is locked on the spindle and will be held against independent movement of any character. In consequence, the tendency of the bobbin to overrun is checked and proper traverse of the thread is insured. The bobbin, when full; may be quickly removed by merely withdrawing the clamping member, and if, for'any reason, it should be necessary to remove the roll, this also may be readily eifected, subsequent to the removal of the clamping member and bobbin, by striking the smaller end of the spindle body sharply with a hammer or similar tool, whereupon the locking disk will be ejected from its seat in the roll face and may be removed by shifting it laterally to bring the outer portion of the slot 6 into alinement with the spindle end; the spindle may then be driven through the roll by striking the free end of its stem.

Both the assembling and the disassembling of the parts may, therefore, be readily effected, as has been explained, and no special tools are necessary, nor will the removal H of the roll occasion drilling or similar operations, such as would be obviously essential if cross-pins or the like be used.

I claim as my invention:

1. A spindle adapted to be passed through the bore of a bobbin and to project beyond said bobbin at opposite ends, said spindle having a plurality of laterally projecting spurs struck up therefrom adjacent one end; a roll mounted on said spindlexand having its bore formed with longitudinal branches wherein said spurs are received, to prevent rotation of the roll upon the spindle, said branches opening through the inner end face of said roll; and a locking disk anchored upon said spindle and engaged with the outer end face of said roll.

2. A spindle adapted to be passed through the bore of a bobbin and to project beyond said bobbin at opposite ends, said spindle having one end thereof threaded and the other end provided with a locking disk which is anchored thereon; a roll mounted on the second-named end of the spindle and having its outer end face formed with a seat adapted to receive said disk; and a clamping member mounted upon the first-named end of said spindle and adapted to be tightened against the adjacent end face of the bobbin,

to draw said spindle in one direction and force said disk into said seat.

3. A spindle adapted to be passed through the bore of a bobbin and to project beyond said bobbin at opposite ends, said spindle having one end of its body threaded and the other end formed with a reduced stem, and being formed at the junction of said stem and body with a retaining recess; in combination with a locking disk anchored in said recess; a roll mounted upon said body directly adjacent said stem and having its outer end face formed with a seat adapted to receive said disk; and a clamping member mounted on the threaded end of said spindle and adapted to be tightened against the adjacent end of the bobbin, to draw said spindle in one direction and force said disk into said seat.

4.
